Im working on project that implements speech recognition on #Raspberry_Pi
I use Bluetooth microphone for audio input and use pulseaudio as driver, but i get low quality sound that make me can't continue further step. Does anyone know how to solve this?

I am using a Raspberry Pi to take a microphone input and filter background noise using a pretrained ML model. I would like to stream the filtered audio to an Android Device and use SpeechRecognizer in Android Studio to transcribe the text. However, from what I've seen in the docs, RecognizerIntent is the only interface for the SpeechRecognizer, which only sources directly from the microphone. Is there any way I can receive the Bluetooth audio as a microphone input so that it can be fed to the SpeechRecognizer?
Today I've connected my bluetooth headphones(Ausdom M08) with PC(via bluetooth dongle).
When I open Skype or Discord I hear no sound on youtube, browser and so on. It only works on Skype and Discord - bad sound, not stereo.
I checked in Sounds Options and I have Ausdom M08 Stereo and Ausdom M08 Hands-Free. First one is default device and second one is default communication device.
When I try to force Skype and Discord to use that default device for sound output I hear no sound then, too!
What I tried:
-Disabling Hands Free Telephony, but I lose microphone function then.
-Tried to uninstall drivers and install again. Still the same.
-Disabling enhancements and exclusive controls of devices.
Literally I tried everything I found on internet or that I thought it can be.
Nothing works.
So the question is: How to make my PC output Stereo Sound from my headphones and still to be able to use microphone from it?
Thanks
There are a lot of missing information here: What PC dongle are you using? Which windows version?
From what I can see about the tech specs of Ausdom M08, it supports few basic profile (HSP/HFP/A2DP/AVRCP). A2DP profile lets you hear stereo audio (Ausdom M08 Stereo). HSP/HFP lets you use the microphone to Skype, but audio is limited to 8K-16K Hz sampling rate (Ausdom M08 Hands-Free). You can't use both Bluetooth profiles at the same time.
So to answer you question: You can't have stereo audio from your headphone while having microphone input.
There are proprietary codec developed by Qualcomm called aptX, which may support microphone over A2DP. But, you'll have to make sure both transmitter and receiver supports this codec.
I am new to PulseAudio and ALSA, so please go easy on me. This might seem like a dumb question, but it is quite important to have it answered.
I am developing application on ARM imx6 board (lets call it BOARD1), with built-in sound card support. With ALSA, I am able to play audio throgh Headset_OUT. But now, we want to move to a new board (lets call it BOARD2), which does not have built in soundcard. But the idea is to connect a bluetooth module to the BOARD2 and have the audio streamed to the bluetooth speaker.
My question is, is it possible to use PULSEAUDIO to send/receive audio to external (bluetooth) audio device without local embedded soundcard (i.e. is it possible to do audio encoding/decoding in just software with pulseaudio and gstreamer combination) ?

I'm working on university project that consists in audio speaker with bluetooth connected to mobile application.
I search a lot possibilities and bluetooth modules that comply my needs, but I have not found any module. I need a Bluetooth module that can receive audio and work in iOS and Android, but I see that a lot of modules with Classic Bluetooth (lowe than 3.0) do not work with iOS, but 3.0 and 4.0 version works with both but are not oriented in audio.
I'm looking for if someone can help me finding one kit with audio receive bluetooth for all plataforms intended for speaker and cheap. Or separately one bluetooth module receiver with 3.0 or upper version (because works in iOS), intended for audio streaming to an speaker, and with some UART pins (tx/rx for example) that can simplify the connection with a microcontroller. And one basic microcontroller oriented to bluetooth receives (with some bluetooth libraries) or simply to program with upp-level language. This microcontroller just receive the audio (bits) and send it to the speaker.
I read too that Smart Bluetooth or Bluetooth Low Energy works on iOS, but can't send audio, have small rate, but i think Smart Ready Bluetooth its possible, but not sure, I have just seen that supports Classic Bluetooth (oriented to audio) and Bluetooth Low Energy, it's possible sens audio with it?
In short, I'm looking for one module Bluetooth 3.o or 4.0 + EDR (that can send audio) for iOS and Android. I find HC05, CC2506X, or HC06 module, but I have read not works in iOS. And a basic microcontroller simply to program to receive this bluetooth audio to send in a speaker.
If someone know one basic kit, or useful information for me I would appreciate.
Thanks.
There is a bluetooth module BC127. it is available at Sparkfun. It dual mode. Means It can work as source and sink both.
Source means, It can Transmit Audio
Sink means, It can receive Audio
Here is link for https://learn.sparkfun.com/tutorials/understanding-the-bc127-bluetooth-module
Any Bluetooth module that acts as an A2DP Sink should work with both iOS and Android.
The specific Bluetooth version that the module implements is not important (as long as it's higher than 2.1), but it needs to be an A2DP Sink (which is only possible over classic Bluetooth)
I have an Arduino Uno and a radio receiver shield (Si4735). I am trying to get another audio source to either play through the currently attached 1/8th jack on the shield or have the audio from the shield piped into the Arduino, where I can redirect it to some other source.
I don't have much experience with Arduino or hardware, however I am very experienced as a software developer. Any suggestions as to where to start, or if this shield even supports either of these functionalities?
Per the schematic, the audio output of the Si4735 chip is wired directly to the headphone jack -- there is no way to send the output elsewhere, or to send other audio to it.
